We dug a trench for the footings when we had an excavator here for the retaining wall, and due to a number of factors have not been able to pour the footings for a number of months. The trench has collapsed, expanded, and become saturated after many months with rain etc. I'm still getting engineering advice on whether to go with a slab or suspended floor on piers - either way the trench is in the line of where the foundation will be. This particular trench will support the wall and also a large bifold door in a steel frame, for which I understand straightness is essential for the smooth operations of a bifold door. The soils are Class M reactive clay, and the site is on a hill sloping 1:7, the lean-to at the rear of my house faces the hill, so cops most of the water coming downhill. Hence the retaining wall. Is there any treatment for a saturated trench? Is the situation salvageable? Thanks for any tips and experience with similar ps the photo shows the other sunroom to the right which we will also most likely demolish to makeway for a clean 9m x 3.8m rectangular box which will be the replacement lean-to.

Could any of these be asbestos? Best to leave as it is or clean up? Thank you for your thoughts 0 381 |
